Subject: [patch 00/10] Linux Kernel Markers for 2.6.21-mm2

Hi Andrew,

He is an updated, folded, version of the Linux Kernel Markers. It replaces the
version found in 2.6.21-mm2 at the exact same spot in the series file.

Main changes :
- It renames the MARK() trace_mark(), as suggested by Christoph Hellwig.
- It now defines the structures contained out of the marker section outside of
  the #ifdef __KERNEL__ so the SystemTAP tool can use the header to extract the
  markers from the kernel binary.
- The i386 optimization has been tweaked a bit : the call is now in the else
  branch. It has something to do with the i386 "fast path" being the taken
  branch of a jump, to make loops faster. It seems that the if/else statements
  are also affected : the if () will be faster than the else. Therefore, I put
  the call in the else, to make sure the fastest path is when the marker is
  disabled.
- I added the blktrace port to the markers infrastructure. It makes one in-tree
  markers user.
